Abstract
The invention discloses a wheelchair capable of conveniently going downstairs, which comprises rear wheels and a rack. A supporting rod is hinged on the back side of the rack. The supporting rod is connected with a protection wheel. The protection wheel rotates along the contour line of the rear wheels. The rotating radius of the protection wheel is larger than the radius of the rear wheels. A compression spring is arranged between the protection wheel and the rack. A GPS (global positioning system) positioning device is additionally arranged on the rack. When the wheelchair goes downstairs, the protection wheel is used as a buffer device to be in contact with stairs and the protection wheel rotates under the effect of the dead weight of the wheelchair to slowly place the wheelchair to the next step; and when the wheelchair stably reaches the next step, the protection wheel is not in contact with the stairs and the protection wheel returns to the initial position under the effect of the compression spring. Since the GPS positioning device is arranged on the rack, disabled people can be tracked and prevented from getting lost.
Description
Technical field
The invention belongs to the technical field of wheelchair, relate in particular to the wheelchair that a kind of convenience is gone downstairs.
Background technology
Along with the continuous increase to individuals with disabilities's love with people that increases of accessible facilities, wheelchair user's range of activity progressively strengthens, but stair are very limited the use of wheelchair.Variously be not widely used in wheeled, lever, the life of crawler type stair climbing wheelchair in reality again, main because their complicated operations, volume and weight is large, price is high.To average family dwelling house bad adaptability, it is its most important factor that is difficult to promote.Therefore, research and development stair climbing wheelchair cheap, that be simple and easy to usefulness is when last more urgent task.
Summary of the invention
The technical problem to be solved in the present invention provides the wheelchair that a kind of convenience is gone downstairs, and under the effect of protecting wheel, wheelchair is delivered to next step lentamente.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: the wheelchair that a kind of convenience is gone downstairs, comprise trailing wheel and frame, be hinged with pole on the dorsal part of described frame, pole being connected with protected wheel, and the described wheel that protects protects the radius of gyration of wheel greater than the radius of trailing wheel along the contour line rotation of trailing wheel, protect between wheel and the frame and be provided with stage clip, also be provided with the GPS positioner on the described frame.
The dorsal part of described frame is the side near the chair back, downstairs the time, normally leaves at last stair near a side of the chair back.
Compared with prior art, the invention has the advantages that: downstairs the time, protecting wheel contacts with stair as a buffer unit, protect to take turns under the effect of wheelchair deadweight, to rotate wheelchair is slowly put to next step, behind next step of steady arrival, protect wheel and do not contact with stair, protect wheel and under the effect of stage clip, get back to initial position; GPS positioner on the frame can be followed the trail of the individuals with disabilities, prevents that it from going astray from the group.
Further, pole is Collapsible structure, can be according to the length of the altitude mixture control pole of stair, thus regulate the radius of gyration of trailing wheel.
Description of drawings
Below in conjunction with drawings and Examples technical solution of the present invention is further specified:
Fig. 1 is the structural representation of the convenient a kind of embodiment of wheelchair downstairs of the present invention.
The specific embodiment
As shown in Figure 1, in the present embodiment, the wheelchair that a kind of convenience is gone downstairs comprises trailing wheel 1 and frame 2, is hinged with pole 3 on the dorsal part of described frame 2, pole 3 is Collapsible structure, pole 3 is connected with protects wheel 4, and the described wheel 4 that protects protects the radius of gyration of wheel 4 greater than the radius of trailing wheel 1 along the contour line rotation of trailing wheel 1, protect between wheel 4 and the frame 2 and be provided with stage clip 5, also be provided with GPS positioner 6 on the described frame 2.
Downstairs the time, protect wheel 4 and contact with stair as a buffer unit, protect and take turns 4 and under the effect that wheelchair is conducted oneself with dignity, rotate wheelchair is slowly put to next step, behind next step of steady arrival, protect wheel 4 and do not contact with stair, protect wheel 4 and under the effect of stage clip 5, get back to initial position; GPS positioner 6 on the frame 2 can be followed the trail of the individuals with disabilities, prevents that it from going astray from the group.Pole 3 is Collapsible structure, can be according to the length of the altitude mixture control pole 3 of stair, thus regulate the radius of gyration of trailing wheel 1.
For a person skilled in the art, under the prerequisite that does not break away from structure of the present invention, can also make some distortion and improvement, these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
